To allgwhom it may concern: l

-Be it known'that 1, JOHN SHELLENBERGER, of North Indianapo1is,-county of Marion, and State of Indiana, have invented a new and -usefullmproved Machine for Feeding Wire andUutting andBending Wire Staples, of which the following is a specification, refer- -enee being hadto the. aceompa'l'lying drawlngs. i i

My invention relates to amachine inwhich the *wire-to be cut and bent is fed to the out- -ti ng-and bending devices, and there cut and bent into staples. V

The ohject of my-invention is to provide a system of newly constructed and arranged devices, havin g new modes of operation, for feeding wire and cutting and bending the same into staples. Q i My invention consists, mainly, in the new construction andarrangement of devices, also in the new combination of old elements, all of which, singly or combined, are deemed essential in my-ne\vlyorganized machine forfeeding wire and cutting and bending the same into staples, all of whichwill be -first any described in the specification, and then set forth 7 in the claims.

In the accompanying drawings, in which like letters of reference'iu the different figures indicate likev parts, Figure '1 represents a perspective view of a machine embodying my invention. Fig. 2 is a top or'plan view of the same. Fig. 3'is'a horizontal sectional view of the same, showing a plan view of that part be- -1ow the upper shaft; and Fig. 4 is a cross-section taken at the line 1 l of Fig. 3, showing the wire-holder and the cutting and bending devices more fully. I

A represents the bed-plate of the machine, on which is mounted the platform J and uprightsB B B B B as shown; The uprights B B stand on the bed-plate A at right angles to the uprights B B Figs. 2 and 3. At the upper part of the uprights B B" the shaft D is supported in suitable bearings, and is provided with a miter-wheel, O, which works in gear with the miter-wheel O, which ison the shaft X, which is mounted in suitable bearings in the upper part of the uprights B Said shaft X is also provided with a belt dated December '2, 1879; application filed wheel, W, by means of which power is applied to operate the machine. r

On the outer end of the shaft visa slnall spur-wheel, H, which works in gear with the large spur-wheel, I. The wheel I is mounted on the outer end of the feed-wheel shaft E on which the cone-shaped feed-roller E is mounted, as shown more fullyin Fig. 3. The

shaft E is provided with a screw t'hrea'd, and

the roller E is made adjustabletoward-either end by the nuts 76 k, as shown. Immediately above the shaft E is another similar shaft with a cone-shaped roller, E," reversed :from the roller E. This shaft and roller are revolved by the roller E and wire g,-and the two rollers are designed to feed the wire g to the cutting and bending devices, which will be hereinafter described.

It is obvious that if it is desiredto feed the wire faster to the cutting and bending devices, the cone-roller E must bevadjusted by the nuts 70 k on the screw-shaft E toward the wheel I, and it the wire is fed toofastthe roller E must be adjusted in theopposite direction.

The wire 9 is wound on a spool, /t,2l.l1(l the spool 71. is mounted in the uprights-d d, as shown. The wire 9 is supported andguided between the feed-rollers E E by the standard Gr, provided with a hole, a, through which the wire is drawn.

The shaft X is provided with a wheel, T, having a cam, U, and groove V, foroperating the discharging device S. (Shown morefully in Fig. 4.) i

The staple-former block P is provided atits front end with a square steel face,- against which wire 9 is clamped by the clalnp-blockL, and held in this position until the'cutting and bending arms It R, which are attached to-the wheel T, out the wire and bend the staples,.as will be hereinafter described.

i The rear end of the staple-formerblock P is provided with a slot in which is fitted the arm P of the discharging device S. ThearmPis pivoted at o, and is constructed similar to that shown in Fig. 4-that is, with the head S for forcing the staples off from the former-block P when bent.

The upper part of the discharging-head S operates in the groove V of the wheel T, and

notch r to come in contact with the wire 9 as it is fed through the hole '5 in the cuttingblock 0. The outer edge of the arm It is made sharp, so as to out against the edge of the block 0, and thus cut 011' the wire g as the clamp L clamps it against the former-block P. The arms R It then pass along the sides of the former-block P, bending the ends of the staple, as shown at p p in Fig. 3, after which the clamp L is released, and the cam U strikes the head S, causing the head to descend and push the staple otf from the former-block.

The clamp L is secured by the set-screw f to the shaft K, which is mounted in suitable bearings in the brackets M M. The bent lever N N is also secured to the shaft K near the bracket-box M. The outer end of the lever N is provided with a coil-sprin g, n, which is fastened at its lower end to the bed-frame A, as shown in Fig. 1. The upper end, N, of the arm N projects back, so as to engage with the roller or lug to, which is secured to the side of the wheel T, as shown in Fig. 2 and more fully in Fig. 4, as the wheel revolves, thus causing the lever to be forced down and bring the clamp L up against the wire 9, and hold it there until the cutters and headers R R cut the wire and bend the staple; then the lug or roller w slips off from the end N of the lever N, and the spring it pulls the clamp L away, thus releasing the bent staple in time for the cam U to operate the discharging-head S and force the staple 01f from the block P.

Having thus described the construction and arrangement of the various parts of my improved machine, I will now proceed to describe its mode of operation, which is as follows, to wit: The wire g is first placed on a spool mounted on the uprights d d and power applied to the wheel W. The wire g is guided between the rollers E E by passing through the hole a of the uprights G. The rollers E E are then operated by their connected gear mechanism, as before described, and the wire is fed through the hole 1 in the cutting-block O in front of the former-block P. When enough wire has been fed to form the staple the roller or lug 10 comes in contact with the lever N, causing the shaft K to rotate and force the clamp-block L up against the wire, thus clamping the wire between it and the former-block P as in a vise. The cutting and bending arms It It then catch the wire in the notches r r, and the arm B cuts OK the wire at the block 0. The arms It R then, as they move backward, bend the ends 12 p of the staple. As the armslt R leave the staple the roller or lug w slips off the lever N, thus releasing the clamp L. At the same time the cam Uoperates the discharging-head S and forces the staple off of the block P. During this operation the rollers E E are feeding more wire to be cut and bent into staples by a similar operation of the machine.

What I claim as new, and desire to secure by Letters Patent, is-

1. The base provided with the uprights I3 B and platform J, combined with the shaft X, the cam-wheel T U, with cutting and bending arms It It, the former-block P, and discharging device S, as and for the purpose specified.

2. The uprights B B, provided with the two adjustable conical feed-rollers E E, combined with guide G and cutter-block 0, whereby the wire is guided and fed to the cutting and bending devices, as and for the purpose specified.

3. In combination with the miter-wheel C on the shaft X and the miter-wheel G on the shaft D, the spur-wheel H, the spur-wheel I, the shaft E provided with a screw-thread and adjustable conical roller E, the adjustable conical roller E, also mounted on a screwthreaded shaft, as and for the purpose specifled.

4. The cam-wheel T, provided with the groove V and cam U, combined with the cutting and bending arms It R, provided with notches 1'1, and discharger I? S, as and for the purpose specified.

5, The former-block I, provided with the pivoted arm P and discharging-head S, combined with the cam-wheel T U and cutting and bending arms It R, as and for the purpose specified.

6. In combination with the cam-wheel T U, with cutting and bending arms It It, and the former-block P, with discharging device S P pivoted thereto, the cutter-block 0, as and for the purpose specified.

7. In combination with the former-block P, the clamping device L, shaft K, lever N N, spring n, and lug or roller w, as and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
